iPhone 4 logic board not sitting right

Hi guys,

I recently replaced the home button and proximity sensor in my iPhone 4 however when assembling it back together I can't seem to get the logic board to fit correctly.

In step 17 of the dis-assembly guide it states that the Logic Board needs to sit under the headphone jack standoff.

I can't for the life of me get it to fit correctly however. Everything else seems to fit fine (I've dis-assembled it multiple times) and nothing looks to block it. The top right hand side of the logic board sits above the circled metal bit when I put it together, causing the Wifi antenna and back case to not fit.

The proximity sensors don't seem to be in the way and the other parts sit flush against the case.

Any idea on what could be causing it?

Is this a good question?

I seem to have resolved it thank you. A large screw from Step 16 above the blue cover was blocking access. I had to undo that screw first and then seat the logic board on it. After that it all went together perfectly.

If you look at the frame of the phone theres a metal clip that sticks up (this is where the wifi cover clips into) It's right underneath the ear speaker. Make sure that this part is behind the logic board and that the logic board is not sitting on it.If it is just use a flathead screwdriver and move it out of the way.
